Well, that's a possibility but the cam sprocket should be pretty tight on the cam in the first place. We Loctite them.

So are we going to get into tech stuff and ruin my stories?

Nope.
Well, maybe.
Just a little.
(Especially when the crusty old Pirate telling the story drops hints of top secret conspiracies with allegations of misdeeds perpetrated against the unsuspecting public.)

"should be" is the operative word but from I have been told, cams timing from the factory has been found to vary to the point of affecting performance significantly. Actually Jim, just before I read your response I meant to come back to this thread and mention how very interesting your story was to read. Enjoyed hearing about it. I'm more of a non- fiction reader because I find the backstories more interesting than any fiction. So please continue. BTW, great party at BG this year.

I agree!

Every now and then you hear little tidbits of how things started and such, but it's nice to have a whole story laid out. Thanks Jim!

JVD,

I'm really not insisting. However, I look forward to hearing the story.

Frank and I are lucky enough to have an LSV = Lingenfelter Super Vette created by LPE for Larry. When GM saw the bowtie logo in the LSV emblem, they made LPE stop using the logo. the plan at the time was that all modified ZR-1s were going to be LSVs.

so really Larry had the only ones. 3 a 385, a 390 and a 368

so when I went up to visit Larry and bought his car, he gave me a bit of this same story that Jim is telling, plus one other tidbit. He claimed that when he took the ZR-1 back numerous times for "recalls" sometimes after flogging the car, sometimes for paint, quality control problems.

on one of his ZR-1s it came back the factory techs had put marbles in the frame. drove him crazy until he finally figured out what it was.

didn't know Larry well, but I'm lucky enough to have one of LPE's finest that Larry passed on to me. has 76k miles now and runs strong as ever.

and thankfully, this one didn't get the marbles!!

The old "coke bottle in the door" story revisited ... best to not pi$$ off a union worker.

Next question - does anybody know what happened to Larry's 1990, the first one he owned?
